Real Circuits

Build actual circuits on a breadboard with an Arduino UNO. LEDs, buttons, buzzers, sensors — real components, real connections, real results.

🧩

Block-Based Coding

Drag and drop code blocks into a guided workspace. Real Arduino C++ appears as you build — see the code, don't just write it.

🏅

Story-Driven Missions

Spy gadgets, dragon alarms, magic harps. Each project is a themed mission that builds real skills — complete it, earn a badge, unlock the next.

How it works

From unboxing to a blinking circuit in your first session.

1

Get your kit

An Arduino UNO, a breadboard, and a handful of components. Affordable and available everywhere.

2

Build the circuit

Follow the step-by-step wiring guide with a clear circuit diagram. No soldering, no guesswork.

3

Write the code

Drag blocks in the browser-based editor. Watch real Arduino code appear as you build.

4

Upload & run it

One click sends your code to the Arduino. Watch your circuit come to life — you built that.

Requires Chrome or Edge · Windows 10/11

New projects, added all the time. Endless fun.

Each mission builds on the last — from your first blinking LED to multi-sensor adventures.

Lights On
💡 Lights On
Your very first circuit. Wire an LED to the Arduino and write the code that turns it on.
Spy Vault
⚡ Spy Vault
Build a combination lock with real buttons and if-logic. Crack the code or trigger the alarm.
Automatic Night Light
🚨 Automatic Night Light
Add a light sensor. Your circuit detects darkness and responds automatically.
Magical Harp
🎻 Magical Harp
Play music with motion sensors. A multi-part adventure combining servos, sensors, and timing.
